MFJ 250
The MFJ 250 Versaload provides a versatile method of loading a RF transmitter. Here is some information about the device to help you get started:
- The oil-cooled resistive element can dissipate 1 KW of RF power and provides low VSWR up to 400 MHz.
- The device requires MFJ Transformer Oil to be filled to within 3/4" of the top for proper oil circulation and cooling. Do not use motor oil, as it does not have a sufficiently high vaporizing temperature and will cause excessive vapor.
- Before operating, study the duty cycle chart in Figure 1 to ensure safe operation.
